Synonymy Miyake & Lindsay (2013) roughly translated, says “The Showa Emperor collected this orangish species from the sea surface and Dr. Tamiji Kawamura described it under the name Sagamalia hinomaru. However, it has been observed at 450m depth on the summit of the Sagami Knoll with its tentacles anchoring it to the seafloor and its float causing it to rise above the seafloor like a hot air balloon. Based on the shape of the bracts we believe that this species should be referred to as Steleophysema aurophora Moser, 1924, which was sampled at the sea surface in Japanese waters, and this would make Sagamalia hinomaru Kawamura, 1954 a junior synonym.” [details]
